Description
Technical field
The present invention relates to the petroleum production engineering mechanical field, specifically a kind of mechanical energy storage-type oil pumper in the oil pumper.
Background technology
The reciprocating beam-pumping unit of at present oil extraction in oil field use has two classes, and a class is the formula of kowtowing or claims beam pumping unit, mainly is comprised of bracing frame, walking beam, balancing weight, pull rope, reduction box, motor, electric machine controller and braking mechanism etc.; Another kind of is vertical oil-pumping machine, and vertical oil-pumping machine mainly is comprised of stand type support, wide belt, belt pulley, balancing weight, reduction box, changement, motor, electric machine controller and braking mechanism etc. especially take belt type pumping unit as main.Reciprocating beam-pumping unit carries in up (carrying oil) process greatly, releasing bearing when descending, and this just need to be equipped with weight block to oil pumper and solve the unbalanced problem of load.Because the balancing weight own wt can not be adjusted, and the load of oil pumper up-down stroke is continuous variation, this just causes, and motor load is unstable, loss serious and do not utilize energy-conservation.Other two kinds of oil pumpers are because the defective of its structure design, also are restricted for the adjustment of oil pumper stroke.
Summary of the invention
Purpose of the present invention is exactly the defective that exists for prior art, and a kind of mechanical energy storage-type oil pumper of stable, energy conservation is provided.
Its technical scheme is: a kind of mechanical energy storage-type oil pumper, on base 12, vertically be fixed with stand 6, stand 6 tops are fixed with leather belt roller 5, belt 7 one ends are walked around leather belt roller 5 and are connected polished rod eye 8, belt 7 other ends connect belt traction mechanism, motor 3 is by electric machine controller 1 control, motor output wheel 2 and the interlock of belt traction mechanism, it is characterized in that described belt traction mechanism is: be fixedly connected with fixing support rack 11 at the two ends of horizontal fixed axis 10, be provided with bearing 16 at the horizontal fixed axis 10 near fixing support rack 11 inboards, bearing 16 outsides connect respectively driving wheel 9 and braked wheel 17, driving wheel 9 and braked wheel 17 inboards are fixedly connected with roller 14, be provided with rigidity wind spring 15 in the roller 14, rigidity wind spring 15 the inners are connected with horizontal fixed axis 10, rigidity wind spring 15 outer ends and roller 14 inwalls are connected, and belt 7 is connected to the outer wall of roller 14, and motor output wheel 2 is connected with driving wheel 9.Described motor 3 is the bidirectional speed governing motor.
Described stand 6 is adjustable for height lifting stand, comprising the lifting stand of peg graft cooperation or module stack cooperation; Horizontal fixed axis 10 is fixedly connected with by pin key 18 with fixing support rack 11; Adopt bolt to fix between driving wheel 9 and the roller 14.Equipped braking mechanism on the braked wheel 17.
The present invention has been owing to adopted the wind spring accumulation of energy to replace balancing weight to adjust the counterweight balance of oil pumper up-down stroke, makes oil pumper whole service process with more stable, and the motor operation is more steady, has both reduced the loss of motor, has saved again electric energy; Wind spring holds and more is conducive to adjust the oil pumper up-down stroke simultaneously; Cooperate the bidirectional speed governing motor, reduction box and changement in the middle of having saved.Compared with prior art, has advantage simple in structure, easy to use, with low cost, that efficient is high.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the present invention;
Fig. 2 be among Fig. 1 A-A to the structural representation of sectional view.
The specific embodiment
As shown in Figure 1, 2, a kind of mechanical energy storage-type oil pumper, on base 12, vertically be fixed with stand 6, stand 6 tops are fixed with leather belt roller 5, belt 7 one ends are walked around leather belt roller 5 and are connected polished rod eye 8, belt 7 other ends are connected to the outer wall of roller 14, and motor 3 is by electric machine controller 1 control, and motor output wheel 2 is connected with driving wheel 9 on the roller.Two ends at horizontal fixed axis 10 are fixedly connected with fixing support rack 11 by pin key 18, be provided with bearing 16 at the horizontal fixed axis 10 near fixing support rack 11 inboards, bearing 16 outsides connect respectively driving wheel 9 and braked wheel 17, driving wheel 9 and braked wheel 17 inboards are fixedly connected with roller 14, be provided with rigidity wind spring 15 in the roller 14, rigidity wind spring 15 the inners are connected with horizontal fixed axis 10, and rigidity wind spring 15 outer ends and roller 14 inwalls are connected.Motor 3 adopts the bidirectional speed governing motor, changement and reducing gear in the middle of can saving.Equipped braking mechanism on the braked wheel 17, this braking mechanism adopt existing mechanism to get final product.
Operating principle of the present invention is: when clockwise rotating (being down stroke) at the driven by motor driving wheel, roller rotates synchronously around solid center dead axle, and the rigidity volume transverse slat of roller inside tightens thereupon gradually, and energy stores by rigidity volume transverse slat.When down stroke reached lower dead center, motor is backward rotation under the control of electric machine controller, and oil pumper begins upstroke.When upstroke begins, when down-hole load also is maximum, this moment, rigidity volume transverse slat also was the position of accumulation of energy maximum, motor and the cooperation of rigidity volume transverse slat lift down-hole load jointly, raising along with upstroke, down-hole load progressively reduces, and rigidity volume transverse slat also is that accumulation of energy is also gradually reducing, and motor remains on relatively stable load condition substantially like this.When upstroke reached top dead centre, the accumulation of energy of rigidity volume transverse slat discharged complete substantially, got back to the starting point of down stroke, and motor begins again to be stored in gradually rigidity volume transverse slat together with the energy of down-hole load.
On the basis of above-described embodiment, adjustable for height lifting stand is adopted in stand 6, such as the stand of vertical grafting engage sleeves cartridge type, or the lifting stand of steel structure module stack cooperation, can adjust like this oil pumper stroke height.Adopt bolt to fix between driving wheel 9 and the roller 14, can adjust the rigidity wind spring winding number of turns in the roller, reach the effect of adjusting balance torsional with this.Set up belt 7 back-up rings 13 in roller 14 neighborings, work to limit the belt trend.
